My girlfriend and I would like to make a solar charger for her Steripen Freedom. The Freedom has an internal lithium polymer battery that can be recharged through a USB port.
Without doing very much homework we bought a 6V, 200mA, 1.2W solar cell, Schottky diode, and female USB port for $9 on ebay.
Here's a picture of the cell, diode, and USB port:
I don't know if this helps, but this is what is says on the back of Steripen Freedom's wall charger.
Has anyone else built a solar charger for a Steripen Freedom?
I don't really know anything about circuitry or electronics and was wondering if someone could point me in the right direction in terms of building the charger, where to attach the diode, if a regulator or additional diode is necessary, etc... I have access to a soldering gun.
